Coimbra and Luso: Portugal’s Historic University and Spa Towns

For travellers who have already stood beneath the gilded rafters of Lisbon’s monasteries and wandered the wine-country hillsides above Porto, Coimbra and Luso offer something quieter but no less rewarding. Coimbra is home to one of the oldest universities in continuous operation anywhere in the world, while Luso is a forest spa town built around a spring the Portuguese have trusted since Roman times. Sitting almost exactly halfway between the country’s two great coastal cities, this pairing rewards travellers who want depth over spectacle. On Days 12 and 13 of our small group Discover Portugal tour, Coimbra and Luso form a deliberate change of tempo between the Fátima region and the wine country of the Douro — a stop built for wandering rather than ticking off sights.

The University of Coimbra’s historic core, seen across the Mondego River.

Coimbra: A University Older Than Most Countries

Coimbra was Portugal’s capital for over a century in the Middle Ages, and it has never quite let go of that gravitas. The reason to visit today is the University of Coimbra, founded in Lisbon in 1290, settled permanently in Coimbra in 1537, and one of the oldest universities in continuous operation anywhere in the world. UNESCO recognised the university’s historic core as a World Heritage Site in 2013, and walking through it, it’s easy to see why: this isn’t a museum reconstruction, but a living campus where students in black capes still cross the same courtyards their predecessors did nearly five centuries ago.

The undisputed highlight is the Joanina Library, commissioned by King João V in the early 18th century. Its three ornate rooms are wrapped floor to ceiling in gilded Baroque woodwork, and the collection housed inside — some 60,000 volumes dating from the 16th to the 18th century — is protected by an unlikely guardian: a colony of bats that lives behind the bookshelves and is deliberately left undisturbed each night to eat the insects that would otherwise damage the pages. Tables are covered with leather each evening for exactly this reason. Access is limited to timed-entry tickets sold in small batches, so this is one stop where arriving early in the day makes a genuine difference.

Beyond the library, the university’s Paço das Escolas (Royal Palace courtyard) offers sweeping views over the Mondego River and the terracotta rooftops of the old town below, while the Baroque Chapel of São Miguel and the ceremonial Sala dos Capelos round out a visit that rarely takes less than half a day.

Conimbriga: Portugal’s Best-Preserved Roman Ruins

For those with an interest in what came before the university, the Roman ruins at Conimbriga, roughly 16 kilometres south of Coimbra, are among the best-preserved in the Iberian Peninsula. Excavated mosaics, bath complexes, and the remains of defensive walls hint at a settlement that thrived for centuries before it was largely abandoned following a Suebi invasion in 468 AD. The on-site museum does a good job of putting the ruins in context, and the site is easily combined with a Coimbra visit for travellers with a full day to spare. Readers who enjoyed the Roman Temple in Évora will find Conimbriga a fitting companion — a second, quieter window into Portugal’s centuries under Roman rule.

Luso: A Spa Town Built Around a Spring

A short drive north of Coimbra, tucked into the pine and eucalyptus forest of the Serra do Buçaco, sits Luso — a town whose entire identity is built around a single natural spring. The waters here have been prized for their purity since at least the Roman period, and by the 19th century Luso had developed into a fashionable thermal resort where Portuguese aristocracy came to take the cure. That tradition continues in a gentler form today: visitors can still drink directly from the public fountain in the town centre, and the surrounding Termas de Luso spa offers treatments built around the mineral-rich water.

Luso’s reputation as a health resort has never entirely faded. The town still operates a medical centre specialising in the treatment of arteriosclerosis — a circulatory condition that becomes more common with age — alongside the more familiar wellness treatments on offer at the Termas spa. Travellers in good health won’t need to seek out any of this, but it’s a reminder that Luso’s identity as a place to slow down and take stock isn’t a recent tourism invention; it’s a role the town has played for well over a century.

The Palace Hotel do Buçaco

The real jewel of the area, however, is a short walk into the forest: the Palace Hotel do Buçaco, a fantastical Neo-Manueline palace built at the turn of the 20th century as a royal hunting retreat, on the site of a former Carmelite monastery. Even travellers not staying overnight can wander its grounds, which include a walled monastic garden, a cross-topped chapel, and some of the oldest planted forest in Portugal — a protected woodland the monks began cultivating over 400 years ago, said to include more than 700 species of trees. The building’s ornate stonework and azulejo-tiled corridors make it worth the detour on their own.

Why This Pairing Works

Coimbra and Luso complement each other precisely because they ask different things of a traveller. Coimbra rewards curiosity and a bit of walking — its old town is built on a hillside, with the university perched at the top — while Luso is built for slowing down, best enjoyed over an unhurried afternoon among the trees. Together they offer a change of pace from the walled medieval streets of Óbidos, the religious solemnity of Fátima and the great monasteries of Batalha and Tomar earlier in a Portugal itinerary, without sacrificing the historical depth that draws travellers to the country in the first place.

Practical Notes for Mature Travellers

Coimbra’s old town involves genuine hills and cobbled lanes, and the university quarter sits at the highest point, so comfortable, sturdy footwear is worth prioritising over convenience. A funicular connects the lower town to the upper university district for those who’d rather not tackle the full climb on foot. Luso, by contrast, is flat and easy walking, with most of its attractions — the fountain, the spa, and the edge of the Buçaco forest — within a few minutes of each other.

Both towns are comfortably reached by car from either Lisbon or Porto in around two hours or less, making this an efficient stop for travellers routing between the two cities rather than a separate detour. Independent travellers should note that public transport between Coimbra and Luso is limited, and a car or organised transfer is the more reliable option for covering both towns in a single day.

Getting There and Fitting It Into a Portugal Itinerary

On our small group tour, Coimbra and Luso sit between the pilgrimage town of Fátima (the base for a day at Tomar’s Convent of Christ, the old Templar stronghold) and the port wine city of Porto, forming a natural bridge between central Portugal’s religious sites and the coastal cities further north. Independent travellers plotting a similar route by car will find the two towns easy to slot in whether travelling north from Lisbon or south from Porto, and both pair naturally with a stop at the Roman ruins of Conimbriga for anyone with a full day rather than a single afternoon to spare. For a fuller sense of how Coimbra and Luso fit into a longer Portugal trip, our complete Portugal travel guide lays out a full 18-day route from Lisbon to Porto, including where this university city and spa town sit within it.

Seeing It for Yourself

This stretch of central Portugal — the university halls of Coimbra, the Roman ruins of Conimbriga, and the forested calm of Luso, where the free day leaves time to walk up to Buçaco — forms one of the more contemplative chapters of our small group Portugal tour, offering a deliberate change of tempo between the energy of Lisbon and the wine country of the Douro. Travelling with a group of up to 16 means the logistics of getting between these two towns, and the visit to the Joanina Library, are handled for you — leaving more time to simply take in seven centuries of history, and perhaps a glass of the water that made Luso famous.
